J. G. SPARKS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORTO HIMSELF AND A. G. BUZBY, OF SAME PLACE.

IMPROVED UARRIAGB-WHEEL.

TO ALL WHOM ITMAY CONCERN:

Be itvknown that I, J. C. SPARKS, of Philadelphia, Pennsylvania, have invented an Improvement in Wheels for Carriages, &c.; and I do hereby declare the following to be a full, clear, and exact description of the same. My invention consists of a ferrule of malleable iron, adapted for v the recepti'on of a tenon on one of the spokes of a wheel, and of projections on the adjacent ends of the felloes, and the inner sides of which are inclined, as fully described hereafter, so that the said felioes may be securely fastened to eaohothcr and to the spoke, while theliahility of the ferrule to become loosened is prevented.

In order to enable others skilled in the art to make my invention, I will now proceed to describe the construction of the same, reference being had to the accompanying drawing, which forms a part of this specification, and in which. i

Figure 1, is a perspective view of suificient of a carriage-wheel to show my improvement.

Figure 2, a sectional view; and I Figure 3, a section on the line 1-2, fig. 2.

A is a square ferrule ofmalleable iron, the inner sides of which are inclined, as shown in the drawing, so that the internal diameteref the ferrule is greater at the ends than at the centre, and in oneside of the ferrule is an opening, 11, adapted forthe reception of a tenon, Z), on meet the spokes B of a wheel. On the adjacent ends of the felloes C C of the wheel are projections c e, in the end of each of which is a recess, 1,, adapted for the reception of a part of'the tenon 6,,the said projections a being of such a size that they may be forced into the open ends of the ferrule; The felloes are placed upon the spokes of the wheel, (except atthe joints where they-meet the spoke 13,) in the usual manner. The ferrule A is then adjusted so that the projections 0 a extend into the open ends of the same, and theend of the tenon 6 projects into the opening a. The ferrule isithe'n driven towards the spoke until theend of the tcnon strikes the inner side of the ferrule, and the ends of the projections c 0 meet on opposite sides of the tenon and enclose the latter, as shown in figs. 2 and 3. The opp site ends of the felloes are then connected in alike manner, and the tire is shrunk round the felloes as usual.

I am aware that a. ferrule having its inner sides so inclined as to form two tapering sockets has been heretofore used, the joint inthis case, however, being between the spokes of the wheel. It will be seen that in the above-described arrangement, the ferrule is adapted for the reception of a tenon on one of the'spokes, and has also inclined sockets forthc reception of projections on the felloes, so that the ends of the said projections, which are recessed to admit tenon, are compressed on and grasp the latter, and form a firm, secure joint at the point where the wheel is generally the weakest. Without claiming broadly a ferrule with tapering sockets,

I claim as my invention, and desire to secure by Letters Patent The arrangement of the ferrule A, having tapering sockets as described, the felloes C C, and spoke B, when projections on the said felloes are recessed for the reception of a teuon on the spoke, which projects through the side of and into the ferrule, all as set forth. I

In testimonywhereefiI have signed my nanie to this specification in the presence of two subscribing witnesses.
